whatever setpoint is available from the terminals (e.g. analog input, selected fix frequencies, etc), and for run
command 101h the setpoint is taken from Input Frequency Setpoint register (when in Frequency mode), or Input
Speed Setpoint register (when in Speed mode).
To setup inverter for automatic stop if communication is lost, it’s possible to use the serial timeout parameter, see
corresponding paragraph in section 5.
Status from inverter is reported in parameter Inverter status which can be read from Modbus register addresses
02A4h and 02A5h. Both will reply the same status code, but reading the former will also trigger an acknowledge of
alarm or fault condition, if such is active. Table below shows code, corresponding text shown on inverter display,
and a short description. The codes in
italic are merely status, while other codes indicate an alarm or fault condition.

6.1.3 Control inverter using DriveControl/DriveStatus
As an alternative to the MODE/SMODE method, it’s also possible to control the inverter in a fashion more similar to
controlling from Profibus/Profinet, using bit field registers for control and status. When using Drive control register,
the inverter takes its setpoint from terminals (e.g. analog) or whatever setpoint is selected using other parameters.
